Proper and optimal storage of pickles... require temperatures to remain at 60 degrees F or cooler, and in a dark place. The shelf life, under these conditions is a maximum of 2 years from the date of manufacturer and 3 months once the jar is opened, but must now be kept in refrigeration. If this is not done, it affects the 'colour' of the pickle and could change the brine, it is stored in, to affect the taste.
